On March 13, an ultra-high voltage branch in Sichuan completed a line channel elimination task in Tanshifang Line channel. This task is to use a new dedicated "tree cutting laser gun" to clean up 500KV Tanshifang line 48#-49# channel in the tree group, these trees are a serious threat to power safety, and because the trunk is very thick, manual cleaning and difficult, the use of cleaning floating hanging objects dedicated laser barrier cutter cutting is almost impossible to cut, so the use of a new tree cutting laser gun remote processing, It's fast and secure.

The tree clearing work was completed with the assistance of Sichuan Red Bank Intelligent Technology Co., LTD. The company is a company specializing in the development and production of electric laser cannons, using its latest research and development of the 6th generation of electric laser cannons, specially designed for clearing power channel trees, raising the traditional laser obstacle clearing instrument to the world's leading level, thus greatly improving the efficiency of tree clearing. Tasks that originally took one or two hours to deal with now only take a few minutes, and the efficiency has been increased by more than 10 times, playing an important role in better ensuring power safety. According to Red Bank base engineers, the use of the new laser cannon is the company through years of research and development of the latest results, all core components are independent research and development, with several aspects of technological innovation, the first is greatly improved portability, weight from the conventional 35Kg to only about 14Kg; The second is the use of a new high-precision self-developed head, response speed and control accuracy and load capacity increased by more than 10 times; Third, the laser spot focus is extremely fine, the power density is greatly improved, and the tree trunk of about 10cm can be broken down and vaporized almost in a moment at the place where the spot is cut.

Through the cooperation of the members and the engineers of the Red Bank Base, they successfully cut the crown of 8 tall trees to the safe distance of the passage. These trunks are very thick, with a diameter of 10-20cm. If the laser obstacle removal device used to clean the floating hanging objects can only handle the branches of 2-3cm thick, cleaning such large trunks is an impossible task. The elimination work is a typical successful case of the ultra-high voltage branch of State Grid Sichuan Electric Power Company using cutting-edge scientific and technological achievements to better protect power safety. Because the efficiency of the new laser gun is much faster than that of manual cleaning, it not only improves the efficiency of the operation, saves the cleaning cost, but also protects the main body of the trunk from being affected, thus protecting the ecological environment, and has high practical value and social value. As a global technology leader, the new tree cutting laser gun will shine in the future in line elimination and protection of power safety.
